' To all whom it may concern Be it known that l, EZEKIEL MARTIN, of Memphis, in the county of Scotland and State of Missouri, have invented a new and valuable Improvement in Oorn-EIarrows; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

The under side of beams on ais provided with har-. row-teeth E, (shown in Fig. 2,) and extensionbeams O are provided with similar teeth E Instead of the rear tooth in each one of said extension-pieces, a knife or shovel, E may be What I claim as new, and desire to secure by Letters Patent, isv A harrow-frame consisting of two rearwardly-converging side beams, on a, and crossbars a a, in combination with vertically and laterally vibrating, extension-pieces G O, which are provided at their rear ends with diverging handles D D, substantially as described, and for the purpose set forth.
